We propose an extension of the law of corresponding states that can be applied to systems—such as colloidal suspensions—that have widely different ranges of attractive interactions. We argue that the “reduced” second virial coefficient is a convenient parameter to quantify the effective range of attraction. Knowledge of the pair-potential alone allows one to estimate the relative location of the liquid–vapor and solid–fluid coexistence curves.

A new electronic transition of is identified near 500 nm by resonance enhanced two photonionization study. The rotational structure shows O, P, Q, R, and S branches. We obtain molecular constants for the upper electronic state of as and By comparison with the ab initio calculated values and from other experimental evidence we assign the observed bands to the transitions of which are allowed by electric quadrupoleradiation.
